4640410 Original Excavator Wire Harness for ZX450-3

Part number 4640410 is the original wiring harness that comes with the ZX450-3 large hydraulic excavator. This harness is a critical signal or power branch harness that connects the core sensors, controllers, and main body harness inside the engine compartment. As the original "nerve endings", their length, interface pin definition, and protection level are completely matched with the equipment layout. It is strictly prohibited to use wiring harnesses with interfaces that do not match, in order to avoid signal interference, functional failure, or short circuits.

This product is an oil and high temperature resistant wire harness with a spiral sheath. The main body is a black spiral corrugated tube, providing excellent wear resistance, compression resistance, and torsion resistance. It is designed specifically for areas with severe vibration and easy interference with components such as engine compartments or chassis. One end is connected to a black plastic waterproof connector with green pins, which may represent specific functions or waterproof levels. The connector itself has a lock to ensure secure insertion. The white label firmly attached to the wiring harness is the core proof of the original factory identity

Daily inspection: Every 500 working hours, check whether the spiral sheath of the wire harness is cracked or worn, and whether the connector is loose, oil or water vapor enters. Fault diagnosis: If the corresponding sensor or function fails, after troubleshooting the main body, you can shake this wiring harness to observe whether the fault reoccurs or measure its conductivity. Replacement timing: When the protective sheath of the wiring harness is damaged, the internal wires are exposed, or the connector pins are corroded or broken, it must be replaced as a whole.
